Abstract

The invention relates to a conveying system having a conveyor belt with a carrying-side and running-side covering plate made from in each case one polymeric material with elastic properties and with an embedded tie beam (17) and with a transverse reinforcement (16) which is arranged within the carrying-side and/or running-side covering plate, wherein the running-side covering plate is supported on carrying rollers, to be precise with the formation of a first section of a conveying system with an elevator conveyor belt and a second section of a conveying system with a pipe-type conveyor belt. The conveying system according to the invention is distinguished by the fact that the transverse reinforcement (16) of the conveyor belt has high elastic elongation with none or with only very low plastic deformation. The transverse reinforcement (16) consists, for example, of individual transverse cords (18, 19, 20) of different length in the transverse direction of the conveyor belt. A conveyor belt of the above-mentioned type is also called a hybrid conveyor belt.

Von besonderer Bedeutung ist bislang CR, das sich durch eine hohe Flamm-, Witterungsund Alterungsbeständigkeit auszeichnet, insbesondere für Fördergurte mit Einsatz im Untertagebergbau. Im Übertagebergbau haben ferner NR sowie die oben erwähnten Verschnitte (DE 10 2009 043 904 AI) eine größere Bedeutung erlangt. Of particular importance to date is CR, which is characterized by a high resistance to fire, weathering and aging, in particular for conveyor belts used in underground mining. In surface mining, NR and the abovementioned blends (DE 10 2009 043 904 A1) have also become more important.
Bedingt durch die Vulkanisation einer Kautschukmischung der oben genannten Art erfährt der Fördergurt die erforderlichen elastischen Eigenschaften. Due to the vulcanization of a rubber mixture of the type mentioned above, the conveyor belt undergoes the necessary elastic properties.
Als eingebettete Zugträger kommen in Fördergurtlängsrichtung verlaufende Seile aus Stahl oder Aramid zum Einsatz, wobei Seile aus Stahl von besonderer Bedeutung sind. As embedded tension members, steel or aramid ropes running in the longitudinal direction of the conveyor belt are used, ropes made of steel being of particular importance.
Insbesondere in Verbindung mit Stahlseil-Fördergurten wird zwecks Schlitzschutz zusätzlich eine innerhalb der tragseitigen und/oder laufseitigen Deckplatte eingebettete Querarmierung aus Synthesecorden, beispielsweise aus Polyamid, verwendet In particular, in connection with steel cable conveyor belts for the purpose of slot protection additionally embedded within the support side and / or running side cover plate transverse reinforcement of synthetic cords, for example made of polyamide used

The tension member may also be a textile fabric, in particular a single-layer or multi-layer fabric, for example a polyester-polyamide fabric.
Wesentliche Bauteile einer Förderanlage mit einem Obertrum und Untertrum sind Essential components of a conveyor system with an upper strand and lower strand are
Trommeln (Antriebstrommel, Umkehrtrommel), Tragrollen und Traggerüste. Weitere Bauteile einer Förderanlage können eine Aufgabeschurre, Umlenkrollen im Bereich des Untertrums sowie Fördergurtprofile aus einem polymeren Werkstoff, beispielsweise Randprofile, sein. Viele Förderanlagen, insbesondere Großförderanlagen, werden heute zudem mit einem Überwachungssystem, beispielsweise mittels Kameraüberwachung oder Röntgenstrahlen, ausgestattet. Zumeist erfolgt die Führung eines Fördergurtes in einer Förderanlage in geöffneter Form, und zwar im Rahmen eines gemuldeten Tragrollenstuhls. Dabei ist aus der Offenlegungsschrift DE 10 2008 045 587 AI bekannt, bei besonders stark beanspruchten Fördergurten eine Querarmierung einzusetzen, die in Laufrichtung des Fördergurtes wenigstens zwei Gruppen von Quercorden umfasst, die sich durch eine unterschiedliche Länge in Querarmierungsrichtung auszeichnen. Ferner wird in der nachveröffentlichten Patentanmeldung DE 10 2010 000 588.6 ein kurvengängiger Fördergurt, insbesondere Stahlseil-Fördergurt, und eine Förderanlage hierzu vorgestellt. Hiernach ist der Zugträger ausschließlich innerhalb des Mittenbereichs des Fördergurtes angeordnet. Zudem ist wenigstens innerhalb der beiden Randbereiche des Fördergurtes ein dehnungsfähiges Gewebe oder in Fördergurtquerrichtung verlaufende dehnungsfähige Einzelcorde aus jeweils einem textilen Werkstoff im Fördergurt eingebettet, und zwar innerhalb der tragseitigen und/oder laufseitigen Deckplatte. Drums (drive drum, reversing drum), carrying rollers and shoring. Further components of a conveyor system can be a feed chute, deflection rollers in the area of the lower run as well as conveyor belt profiles made of a polymeric material, for example edge profiles. Many conveyor systems, especially large conveyor systems, are now also equipped with a monitoring system, for example by means of camera surveillance or X-rays. In most cases, the leadership of a conveyor belt takes place in a conveyor system in an open form, in the context of a domed carrying roller chair. It is from the Publication DE 10 2008 045 587 AI known to use in cross-armament particularly heavily loaded conveyor belts, which comprises in the running direction of the conveyor belt at least two groups of cross cords, which are characterized by a different length in Querarmierungsrichtung. Furthermore, in the post-published patent application DE 10 2010 000 588.6 a curved conveyor belt, in particular steel cable conveyor belt, and a conveyor system is presented for this purpose. Thereafter, the tension member is arranged exclusively within the central region of the conveyor belt. In addition, at least within the two edge regions of the conveyor belt, an extensible fabric or stretchable Einzelcorde extending in Fördergurtquerrichtung from each textile material embedded in the conveyor belt, and indeed within the support side and / or running side cover plate.
Gemuldete Fördergurte zeichnen sich durch eine hohe Förderleistung und einen geringen Energieverbrauch aus. Gemuldete Fördergurte müssen möglichst eben (plan) sein. Dies wird durch die gewöhnliche Bauart problemlos gewährleistet. Die Fördergurte liegen üblicherweise auf drei- oder fünfteiligen Tragrollen. Das Fördergut liegt angehäuft und ungeschützt auf der tragseitigen Deckplatte des Fördergurtes. Troughed conveyor belts are characterized by a high flow rate and low energy consumption. Tolled conveyor belts must be as level as possible. This is easily ensured by the ordinary design. The conveyor belts are usually on three- or five-part idlers. The conveyed material is piled up and unprotected on the support-side cover plate of the conveyor belt.
In den letzten 20 Jahren ist jedoch das geschlossene Fördersystem unter Einsatz eines Rohrfördergurtes entscheidend weiterentwickelt worden. Innerhalb der Ein- und In the last 20 years, however, the closed conveyor system has been decisively developed using a tubular conveyor belt. Within the inputs and
Auslaufstrecke ist der Fördergurt wie bei den konventionellen Gurtförderern gemuldet. Auf der Transport- und Rücklaufstrecke schließt sich jedoch der Fördergurt und bildet eine Röhre (Rohrfördergurt, Schlauchgurt, Rollgurt). Für dieses Transportsystem werden ringförmig angeordnete Tragrollen sowie gegebenenfalls zusätzliche Korrekturrollen benötigt. Neben den konventionellen Gurtförderern zeichnet sich das geschlossene Transportbandsystem durch folgende Vorteile aus:  Outlet line is the conveyor belt as in the conventional belt conveyors tolerated. On the transport and return line, however, closes the conveyor belt and forms a tube (Rohrfördergurt, Schlauchgurt, Rollgurt). For this transport system annularly arranged support rollers and possibly additional correction rollers are required. In addition to conventional belt conveyors, the closed conveyor belt system has the following advantages:
- es ist besonders kurvengängig; - it is especially curvy;
- es hat eine besonders hohe Steigfähigkeit; - es ist platzsparend; - it has a particularly high climbing ability; - it saves space;
- es schützt das Fördergut sowie die Umwelt, beispielsweise bei Staub oder - It protects the conveyed goods as well as the environment, for example with dust or
radioaktivem Fördergut.  radioactive material.
Wichtig ist, dass sich Rohrfördergurte leicht zu einem Kreis formen lassen, um die Bewegungswiderstände durch hohen Anpressdruck an die umgebenden Tragrollen gering zu halten. Rohrfördergurte nehmen im Lauf der Zeit durch bleibende Verformung der verarbeiteten Komponenten die runde Form an, was in der Regel vorteilhaft für die Funktion und den Energieverbrauch des Fördergurtes ist. It is important that pipe conveyor belts can easily be formed into a circle, in order to keep the movement resistance low by high contact pressure on the surrounding carrying rollers. Tube conveyor belts will eventually become round in shape as a result of permanent deformation of the processed components, which is generally advantageous for the function and energy consumption of the conveyor belt.

Anwendungen, in denen der Einsatz beider Fördergurtausführungen, nämlich eines Muldenfördergurtes und eines Rohrfördergurtes innerhalb bestimmter Anlagenabschnitte gefordert werden, nehmen zwischenzeitlich zu, wobei insbesondere auf folgende Beispiele verwiesen wird: Applications in which the use of both Fördergurtausführungen, namely a Muldenfördergurtes and a Rohrfördergurtes within certain sections of equipment are required, are increasing in the meantime, with particular reference to the following examples:
- Gewünscht ist diese gemischte Anlagenkonzeption bei der Überquerung von Flüssen und Tälern, wo wegen der Gewichtsgrenzen keine Abdeckungen der Förderanlage möglich sind. Ein Rohrfördergurt schützt das Fördermaterial wie auch die Umwelt. Das Gleiche gilt auch für windreiche Strecken. - Nur Teilbereiche der gesamten Förderanlage liegen in Kurven. Bisher werden solche Fälle mit einer Aneinanderreihung von Muldenfördergurten und Rohrfördergurten, die mittels Fördermaterialübergaben verbunden sind, gelöst. Diese Übergabestationen sind jedoch teuer, wartungsintensiv und zudem sehr verschleiß fördernd. - This mixed system design is desired when crossing rivers and valleys, where due to the weight limits no covers of the conveyor system are possible. A tubular conveyor belt protects the material as well as the environment. The same applies to windy routes. - Only parts of the entire conveyor system are in curves. So far, such cases are solved with a juxtaposition of Muldenfördergurten and Rohrfördergurten, which are connected by conveying material transfers. However, these transfer stations are expensive, maintenance-intensive and also very wear-promoting.
Die Aufgabe der Erfindung besteht nun darin, eine Förderanlage bereitzustellen, dessen Fördergurt derart gestaltet ist, dass dieser sowohl die Form eines Muldenfördergurtes als auch die eines Rohrfördergurtes annimmt (Hybrid- Fördergurt). Gelöst wird diese Aufgabe dadurch, dass die Querarmierung des Fördergurtes eine hohe elastische Dehnung bei keiner oder nur sehr gering bleibender Verformung aufweist. The object of the invention is now to provide a conveyor whose conveyor belt is designed such that it assumes both the shape of a Muldenfördergurtes as well as a Rohrfördergurtes (hybrid conveyor belt). This object is achieved in that the transverse reinforcement of the conveyor belt has a high elastic strain with no or only very small remaining deformation.

Bislang wurde PEI bevorzugt zu Kunststoffteilen für die Elektronik und in der  Polyamide (PA), for example PA11 or PA12, or of a polyimide (PI), wherein the polyetherimide (PEI) is particularly noteworthy here. The PEI is a high-performance thermoplastic belonging to the group of high-temperature-resistant plastics. So far, PEI has been preferred to plastic parts for electronics and in the

The transverse reinforcement is here in particular in a cord construction, either in the form of Einzelcorden or a Cordgewebes. The cord fabric comprises transverse cords and warp threads (auxiliary threads) running in the longitudinal direction of the conveyor belt, which consist for example of a polyester.
- Die Querarmierung besteht aus einem Formgedächtniswerkstoff, der derart beschaffen ist, dass die Rückstellung in die Ausgangsform, die sich auf die gestreckte Lage bezieht, durch Einwirken eines externen Impulses möglich ist, beispielsweise mittels eines Magnetfeldes oder bei einer bestimmten Temperatur oder unter optischen Einflüssen.

Fig. 4 zeigt eine Querarmierung 16, bestehend aus Einzelquercorden 18, 19 und 20, die quer zum Zugträger 17 angeordnet sind. Diese Einzelquercorde, die wiederum 4 shows a transverse reinforcement 16, consisting of individual transverse cords 18, 19 and 20, which are arranged transversely to the tension member 17. These single crosses, in turn
insbesondere aus PEI bestehen, zeichnen sich in Fördergurtquerrichtung durch eine unterschiedliche Länge aus. Dabei treten im Rahmen eines sich stets gleichmäßig wiederholenden Anordnungsprinzipes drei Querarmierungsgruppen auf, nämlich: in particular consist of PEI, are characterized in Fördergurtquerrichtung by a different length. In the process, three cross arming groups occur within the framework of an always uniformly repeating arrangement principle, namely:
Einzelquercord 18: lang (im Wesentlichen über die gesamte Fördergurtbreite) Single Cross Cord 18: long (essentially over the entire conveyor belt width)
Einzelquercord 19: mittellang (nichterfassend die beiden Gurtrandbereiche) Single Quercord 19: medium long (not including the two belt edge areas)
Einzelquercord 20: kurz (nur den Gurtmittenbereich erfassend) Single cross cord 20: short (only detecting the belt mid-range)
Auch eine Querarmierung mit zwei Querarmierungsgruppen, beispielsweise aus den Einzelquercorden 18 und 20, ist eine mögliche Querarmierungsvariante. Also, a transverse reinforcement with two Querarmierungsgruppen, for example, from the Einzelquercorden 18 and 20, is a possible Querarmierungsvariante.
Das in den Fig. 3 und 4 dargestellte Querarmierungskonzept ist auch auf The Querarmierungskonzept shown in Figs. 3 and 4 is also on
Formgedächtniswerkstoffe anwendbar. Shape memory materials applicable.
